San Diego River Tidal Mudflats & Famosa Slough Trip Report

Day started overcast, but quickly cleared with temperature in the low 80’s. We had between 35-40 birders, with one out of town birder from the Bay Area. It was several hours before low tide, so only two mudflats were exposed and one of them was overrun with dogs off of their leash. The best bird was a Red Knot still showing red in the chest. One Common Tern was seen by a few and a Foster’s/Common Tern seen and debated by many. Only about 15 birders continued to Famosa Slough which was most unbirdy. Best sighting was two flyovers of Red-masked Parakeets.

Between the two sites, we had 51 species.
